It is capable of completing its entire life cycle on the host. Roosters tend to maintain higher populations of mites than hens (Maw et al., 1935; Abasa, 1965; Matthysse et al., 1974). Matthysse et al. (1974) found a strain mite ( Ornithonyssus sylviarum) in that nest will be presented.

These, plus the deutonymphal instar, do the same in D. gallinae. A second important difference between both species is their way of life at least in poultry: O. sylviarum acts as a typical ectoparasite, completing its entire life cycle on the host, so that a Knowledge of the life-cycle, host preference and synanthropic presence of these two dermanyssoid mites raises the question of whether long-distance natural bird migration and/or human activity (animal trade, transportation) may be responsible for the local introduction of D. gallinae or O. sylviarum. Gamasoidosis or dermanyssosis is a frequently unrecognized ectoparasitosis and source of growing concern in human medicine, occurring after contact with avian mites which infest canaries, sparrows, starlings, pigeons and poultry and caused by two genera of mites, Ornithonyssus and Dermanyssus. Ornithonyssus sylviarum mites, hen Scaly leg mite infestation The most economically important of the many external parasites of poultry are mites of the families Dermanyssidae and Macronyssidae (poultry red mite, northern fowl mite, and tropical fowl mite) and Trombiculidae (turkey chigger). posterior end tapers acutely in Ornithonyssus sylviarum but more evenly in Ornithonyssus bursa. There are three pairs of setae on the sternal plate in Ornithonyssus bursa and only two pairs in Ornithonyssus sylviarum.

Apply no more than 1 gallon of coarse spray per 100 birds to ensure adequate coverage, directed toward the vent area.

During heavy infestations, NFM can cause the chickens a great deal of The Northern fowl mite (Ornithonyssus sylviarum) is the most common external parasite found on poultry. It feeds on blood and can cause anemia if the poultry is heavily infested. The mite’s development from egg to egg-laying adult takes about one week under optimum conditions—cool months are more favorable than warm ones.

Avian mite species implicated include the red mite (Dermanyssus gallinae), tropical fowl mite Ornithonyssus bursa, otherwise known as the tropical fowl mite, is a common ectoparasite of domestic and wild birds in tropical and subtropical regions worldwide. In the United States, it's found in the eastern and southern states.

Gamasoidosis or dermanyssosis is a frequently unrecognized ectoparasitosis and source of growing concern in human medicine, occurring after contact with avian mites which infest canaries, sparrows, starlings, pigeons and poultry and caused by two genera of mites, Ornithonyssus and Dermanyssus.

There are three pairs of setae on the sternal plate in Ornithonyssus bursa and only two pairs in Ornithonyssus sylviarum. Life Cycle This mite’s life cycle is similar to the northern fowl mite.

Newly infested birds can support populations exceeding 20,000 mites in 9-10 weeks. Mites can survive 2-3 weeks off the host.3 The northern fowl mite is the most common external poultry parasite. Left unchecked, One application of Elector PSP at recommended levels can break the life cycle and control northern fowl mites.2 In addition, Elector PSP poses no cross-resistance issues for producers who use pyrethroids, carbamates or organophosphates. Treating for northern fowl mites in caged layers (Ornithonyssus sylviarum) Elector PSP proper use guidelines • Life cycle stages including eggs, 6-legged larval, and 8-legged nymphal and adult stages. • Causes sever itching, especially upon subsequent infections.

The NFM has five life stages; egg, larva, protonymph, deutonymph, and adult. The protonymph, deutonymph, and adult stages have eight legs while the larval stage has only six. The protonymphs and adults blood feed, and an adult female usually produces 1-3 eggs from one feeding. Image of mature NFM (O. Sylviarum), approximately.5 mm in length, X63 magnification.

Background: Northern fowl mites (Ornithonyssus sylviarum) are obligate hematophagous ectoparasites of both feral birds and poultry, particularly chicken layers and breeders. They complete their entire life-cycle on infested birds while feeding on blood.
